!!!!Description

Unsigned long variables are extended size variables for number storage, and store 32 bits (4 bytes). Unlike standard longs unsigned longs won't store negative numbers, making their range from 0 to 4,294,967,295 (2^32) - 1).

!!!!Example

[@
long time;

void setup(){
Serial.begin(9600);
}
void loop(){
Serial.print("Time: ");
time = millis();
//prints time since program started
Serial.println(time);
// wait a second so as not to send massive amounts of data
delay(1000);
}
@]
!!!!Parameters

[=long var = val;=]

*var - your long variable name
*val - the value you assign to that variable
